Default W3-881SI tabaq

Will the W3-881SI be a good speaker for the tabaq box design on http://coolcat.dk/bjoern/TABAQ_TL_for_TB.pdf

I tried modeling the specs but I am very new to this and was less then successful at gaining any real info.
I did do a ported box tuned to 49.5hz and it looks good to me but I will post so someone can correct me. I put in all the specs I could find for the speaker.

Hi,

Consider an upgrade to winISD Pro. You get other features such as an excursion chart for the power input, which is very useful for small drivers.

However, this software can't model transmission lines. You're going to either need a different piece of software, or take your chances with the design: the author suggests using drivers with a high Fs and Qts, so you'll be okay there.

I built a sealed box for the speakers and they do sound good for what they are but I wouldent want them for my main speakers.
I do think the speakers have more potential.

I realize that this thread is a bit stale, but I just completed a TABAQ build using the w3-881sjf with amazing results. I cannot recommend highly enough. Previously I had Acoustat electrostatics and klipsch rf-52 mkii on this system, but these TABAQs are by far the most fun to listen to. Effortless bass that seems to roll off perfectly, very natural sounding with awesome imaging.Click the image to open in full size.Click the image to open in full size.

Hi ChairmanMAO

Nice job with a great finish. I am glad you like the result. I also find the imaging is very good.

ChairmanMAO,

Very nice looking pair of TABAQs - how did you apply the paint?

I built a pair of folded TABAQs a few weeks back with Tang Band W3-1053sc drivers and like you was surprised by the sound. They are placed close to the wall and running without any filter.

Thanks for the kind words everyone!
This was my first time working with MDF and the second pair of speakers I ever built.
Definitely learned a lot that will make future builds easier.

Zman,
First thing I did to MDF was give it a skim coat of drywall joint compound and then sand with 220 sandpaper to make smooth, followed by 2 coats of oil based primer again sanded with 220 when dry to make smooth, now for the labor intensive part...I used rustoleum oil based paint mixed 50:50 with mineral spirits to thin it down.
Then this was my paint sequence:
2 coats of paint, sand with 220
2 coats of paint, sand with 400
1 coat of paint, sand with 800
1 coat of paint, wait 1 week, sand with 2000, rubbing compound and then polish.
I am going to wax them after a month when I am sure paint is fully cured.
I never listened to the speakers before I applied the finish, I was really concerned I would have all this work in them and not like the sound, thankfully that wasn't the case, and now I'm proud of my first attempt at MDF finishing. Also, I recommend the filter after listening both ways.

Next build I am going to use wood veneer! Should make life easier. Hoping to build a project called the flat5 TL using the w5-1611. Although Bjorn's TABAQ for the W5 looks tempting, the flat5 is visually appealing to me with the wide baffle
